Question

An object under goes an accelation of 8m/sec sqaure starting rest .find the distance travel ed in 1 sec

Answer 1

a=8m/s^2
u=0m/s(object starts from rest)
t=1 second
$s = ut + \frac{1}{2}at {}^{2} \\ = 0 \times 1 + \frac{1}{2} \times 8 \times 1 {}^{2} \\ = 0 + 4 \\ = 4$
So, the distance travelled in 1 second is 4 metres.
